Research interests

Chronic Kidney Disease (CKD) is a devastating condition that affects more than 1.8 million people in the United Kingdom. Despite current treatments, a significant proportion of patients progresses to end stage renal failure which requires lifelong dialysis or transplantation, underlining the urgent need for new therapies. During CKD, the kidney gradually becomes unable to sufficiently filter the blood. One of the main cells responsible for the ultrafiltration are podocytes which are comprised of a cell body extending many projections, called foot processes, wrapping around the capillaries in the glomerulus. These processes interdigitate with each other forming a critical component of the filtration barrier. The actin cytoskeleton is responsible for maintaining the structure of the foot processes and during disease, the actin cytoskeleton becomes disorganised and foot processes lose their specialised shape and structure. Thymosin -4 (TB4) is the main G-actin sequestering peptide in cells with a critical role in maintaining the actin cytoskeleton. Previous studies from our group have shown that loss of TB4 in podocytes exacerbates kidney disease and disrupts the actin cytoskeleton of the podocytes. My research is focused on the therapeutic potential of exogenous TB4 on injured podocytes in vitro and in vivo. We hypothesise that TB4 will be able to protect kidney function by preventing the cytoskeletal rearrangements in podocytes.
